Nacho Monrealâ€™s opener against Ostersunds FK meant he has been directly involved in five goals in his last six games for Arsenal in all competitions.

Then the home sideâ€™s centre-back Sotirios Papagiannopoulos diverted Henrikh Mkhitaryanâ€™s cross into his own net after the Armenian seized on a loose pass.

Ostersund improved after the break but any revival was ended by Mesut Ozil, who made a well-timed run into the area and squeezed his shot past Keita for the third, before the hosts had a late penalty saved.
